Beware the EV

Was it 70 people killed 2 days ago when a leaking petrol tanker caught fire?
Not an uncommon ocurrence either.
I guess that is OK?
Cheers,

Not quite the whole story. here is what aap factcheck has to say about the above video.

Chinese electric cars are on sale here.

There are so many factual inaccuracies in that furphy that even the parts slightly true have no meaning or value. Besides, EV fire rates are lower than ICE fire rates, whether it's fires per number of sales or fires per km travelled.

Guess so if you steal petrol from a rolled over fuel truck while many in that crowd were smoking, hardly relates to that vid posted here.

A lit cigarette will not ignite petrol,as proven to me by a mechanic friend of mine,who regularly "puts out" his cigarette in a bowl of petrol alongside him,in his workshop.Obviously not something to be encouraged,but he always makes sure,when he lights another cigarette,that he is away from any petrol fumes.Cheers

Any time 20,000 litres of petrol spills in a populated area, it is going to explode and many people will likely be killed, whether they were stealing it or not.

Geez you blokes go off track easy, who cares if a cigarette will ignite petrol or not , how did he light the smoke, a match? where did he throw it? people fall off the perch everyday for one reason or another.

Moral of the story, it was in China not Germany big deal, 2 underground carparks in Germany did ban EV's for a period of time and then allowed them again. And batteries can catch fire !!!!

Now go and leave your cheap 12v Chinese made cordless drill on charge overnight and burn your shed down.

Merry Christmas

The moral of this story is to not post misinformation on a regular basis as people become sceptical of such crap when we are getting it day in day out, but some don't give a hoot they just want to see who bites.

Maybe it's time to switch away from Lithium-ion batteries to something else. I don't remember if the Lithium-sulfur batteries are less likely to burn but they seem cheaper to make and hold more charge:

https://www.abc.net.au/news/science/2021-09-14/batteries-lithium-sulfur-sugar-future-electric-vehicles/100457492

I do know that the new Aluminium-ion batteries 'don't explode' but may not hold enough charge:

https://www.alphr.com/power-supplies/1000599/stanford-universitys-aluminium-ion-battery-is-a-breakthrough-but-its-not-a

There're a lot of different battery technologies being developed. Hopefully some of them will overcome this perceived idea that batteries are more dangerous than fossil fuels and they are cheaper, safer, less flammable, hold more charge, charge faster, etcetera, etcetera. We want it all!

What we need is an entrepreneur to take up the production of the new technologies. Unfortunately Twiggy is too busy with Hydrogen to help. ;-)

Given the number of petrol powered vehicles verses battery powered, I would say YES!

Aus-Kiwi · Guru

Depends how many are standing around ? I wouldnt imagine too many standing around an EV before it caught fire ? The issue actually is they are bloody hard to put out ! We as humans will work our way around this !! I hope !! Just dont be to narky or negative !!

Peter_n_Margaret · Guru

Shifting 20,000L of petrol around the country in tankers is always gong to be more danderous that the occasional EV fire. And the safety systems will rapidly improve for those.

Last night I watched a show called: Guy Martin: The World's Fastest Electric Car.

https://m.imdb.com/title/tt15173782/

It had many answers to this discussion. For example, modern EVs have fuses that prevent them from catching fire like the video.

It's worth a look even if you are a petrol head. The electric Beetle beats a McLaren 570S in a quarter mile race.

A fuse is not going to stop a battery that has a cell that has melt down from catching alight.

Watch the show. You'll be surprised what they do to a battery to try and get it to burn.

All these speed trials to say how great they are to which they are ! But like all things ! They are not perfect ! Seeing nearly every one is into SUVs . What the hell does 1/4 mile times have to do with a family going on a trip . So far they are GREAT for local driving with in 100klrs from home . Which is in most cases what 80% of our travels are . Going to work . Picking kids up from school, shopping etc I think the fire issues can be improved by having fusible links between battery packs ?

I expect from your comments that you haven't looked at the show. There're a lot of information. Some contradicts what you say.

Hes probably like me, got lost in the crap looking for the video, one i did find was way too long to be bothered.

Yes. I can't find the whole show in one video. One might have to use SBS On Demand

Here's a video about trying to get modern batteries to 'explode':

Jon Faine recently had a fire in his E Type Jag. Suspect is a probable faulty ammeter whilst it was just sitting in the shed.

Aus-Kiwi · Guru

I guess he couldnt get it to fire up ?

Craig1 · Guru

lucky he covered the dash in foam from $20 extinguisher, but have heard that stuff is very difficult to clean off and can damage bits. The ammeter was showing a small discharge at all times. He says he checked it with a multi meter and there was no discharge, however?

Did the Jag burn like in the video of the original post?

In my entire life I have never known anyone to park a tanker with 20000 litres of petrol in their carport or garage at home and then plug in a power point to charge a battery.
I hope that this is not the new trend.

Craig1 · Guru

Buzz, mostly smoke, a little flame and then out, fire men attended and monitored temps until safe. He said one firie wanted to smother the whole car. Lucky the man in charge stopped him. Apparently their stuff totally stuffs cars.

Buzz Lightbulb · Guru

The original posted video seems to be old technology. Either that or the Chinese cars haven't yet adopted the new, fused batteries.

An ideal ammeter presents itself as an inline short circuit to the current being measured. The only scenario I can think of that would result in a fire is if the connections to the shunt were to come loose. The load current would then be diverted through the meter movement and burn it up.
